MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 451,299, dated April28, 1891.

Application filed July 26, 1890. Serial N0.360,038.7 (No model.)

To aZZ whom it may concern.-

Be itknown that 1, WILLIAM W. CONDER, of Tillamook,in the county ofTillamook and State of Oregon, have invented a new and ImprovedMilk-Oooler, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in milk-coolers, and is intended asan improvement on the device for which I filed an application forLetters Patent of the United States October 2, 1889, said-applicationbeing numbered 325,743 and allowed December 2, 1889.

The object of my invention is to provide means whereby the cover of themain tank and the covers of the milk-receptacles may be easily operated,and also to provide a simple arrangement to permit the escape of animalheat from the milk in the milk-receptacles.

To this end my invention consists in certain features of constructionand combinations of parts, which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a broken perspective View of the tank and milk receptacles,showing the tank-cover open. Fig. 2 is a front elevation of the same,and Fig. 3 is a broken transverse section of. the device with thetankcover closed.

The tank A is provided with milk-holding vessels G, which are united atthe bottom into a common receptacle, as shown and described in my formerapplication above referred to. The cover B is hinged to'the tank A, asdescribed below, and on its 7 under surface are depending flanges C,adapted to fit closely upon the vessels 0 and serve as covers for thesame, the above-described parts being substantially as shown in myformer application and forming no part of this invention.

A rod (1 extends across the back portion of the tank A, near the upperend thereot,-being pivoted in suitable keepers, and each end of the rodis bentto form the part a, which extends parallel with the sides of thecover B, said parts having suitable eyes 0. by means of which they areattached to the cover. On

one side of the coverB the rod a is also formed into a depending arm ahaving a terminal eye at", which engages or interlocks with an eye d'ofthe rod d, said rod having its lower end formed into a terminal eye 01which is pivoted by a screw 6 to the rear side of the tank A, and havingits upper end formed into a suitable crank d so that by moving the crankthe rod 01 and the part a of the red at will be moved and the cover Braised or lowered, as the case may be.

The rods 00 and d are formed preferably of iron of sufficient strengthto bear the Weight of the cover, and it is obvious that the shape of therods may be changed without departing from the principleof my invention,and that a greater or less number of members may be used.

A pipe D projects through the cover B,being centrally fixed therein,said pipes having its lower end provided with branch pipes D, which openfrom said pipe into the flanges or covers 0 of the various milk-holdingvessels- O. The pipeDprojects above the upper surface of the cover B, isscrew-threaded, as shown, and provided with a suitable cap D .which isinternally screw-threaded, so as to fit nicely upon the upper end of thepipe D. It will thus be seen that when the cover 13 is closed theflanges G will fit closely upon the milk-holding vessels C, and that byremoving the cap D from the pipe D the animal heat from the milk in thevessel 0 will pass through the branch pipes D and pipe D and into theouter air. It will also be found in practice that the arrangement of therods a and d will permit the easy operation of the cover B, and that theconnected ends of said rods will press against the sides of the tank andhold the cover B in position thereon. In practice the tank A is filledwith cold water in the manner described in my former application.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a milk-cooler, the combination, with a tankcarrying milk-holding vessels, and a cover hinged to the tank andprovided with depending flanges adapted to inclose said vessels, of apipe centrally fixed in the cover and on the tank and provided with armsa, having eyes a thereonpvhich are fixed to the sides of the cover, andthe member a depending from the cover B and formed into a terminal eye(1 and the rod d, having an eye d to engage the eye a an eye (1 pivotedto the side of the tank, and asuitable crank d by means of Which therods a and (Z and the cover B may be operated, substantially asdescribed.
